I have checked smb now but nothing relevant in the folders that can be accessed with user Anonymous:

Let's take a look through the browser, port 80 and 443 have nothing interesting, while on port 8080 we find:

So, we have oscommerce 2.3.4, apache 2.4.23 on win 32 bit with PHP 5.6.28.
Great let's look in the folders:

the links on this page do not work, the search does not work, so let's start dirsearch with the command:

dirsearch -u http://blueprint.thm:8080/oscommerce-2.3.4/ -e php,cgi,html,txt -x 400,401,403 -r -t 100

Among many things I look at the Install folder

I check on exploit-DB what exploit I find for this version of eocommerce:

Great we have two RCEs and an arbitrary File Upload!

Let's check the 50128.py Remote Code Execition exploit first:

ok, i have a shell and i'm NT Authority/system but i can't do anything else, so i just verified that it's possible to do it, let's go to the next exploit the 43191.

However for this exploit we need credentials, so let's visit the /install page.

Bingo, let's try to follow the procedure!

We set the DB, which as per XAMPP documentation should be empty for the root user:

it works we proceed and finish the procedure!

Well we are in the back end with the credentials of administrator admin:admin so we try the exploit 43191.

works by visiting the shell url

the idea was to view from here and launch a reverse shell but this does not work, so let's try uploading a reverse shell PHP version by Ivan Sincek that you can find at this page.

..after some testing...

load the shell and keep active multi/handler of metasploit, in this way the reverse shell will be loaded and executed then it will launch a connection in msfconsole.

ok so we are in the vm as nt authority\system we look for the administrator flag:

Now we have to find and decrypt the NTML of the user "Lab".

We do the upload of mimikatz through certutil, of course I loaded mimikatz 64 bit version that does not work so I proceed with the 32 bit version.

now let's get it started

room solved! Thanks
